Abstract

A method for the injection-moulding of articles comprising at least two different layers (10,14) provides that at least one layer, preferably the outer layer (10), is produced from a lacquer. This can be achieved with an apparatus in which a mould (9) is preceded by at least one main injection assembly (2,3) having an injection unit (7) allowing the injection-moulding of multilayered articles.
